The Dutch word 'morgen' meaning tomorrow has nothing to do with the morgen Wiktionary page so I removed the link. maybe that's also true for other languages but I can't be sure.
"30 years tomorrow"
I saw a curious construct today in The Register : "[The Jupiter Ace computer] first went on sale 30 years tomorrow." I can see similar much older usages in Google Books, e.g. "Do you remember that it is 30 years tomorrow since Sidney Herbert died?" Equinox ◑ 10:32, 21 September 2012 (UTC)
